To all whom it may concern: 1

Be it known that l, WiLnni ll. SELF, a citizen of the United States,;residing at Newton, in the county of Catawba and State of NorthCarolina, have invented a new and useful Device for Ventilating Hotelsand Oiiice-Buildings, of which the following is a specification. I

The device forrnin the subject matter of this application is adapted tobe employed for ventilating hotels, oilice buildings and otherstructures, and the invention aims to provide a simple but efiicientmeans whereby proper ventilation may be secured in super posed rooms'orcompartments of a building.

It is within the rovince of the disclosure to iinprov'e generally and toenhance'the utility of devices of that type to which the presentinvention .appertains.

With the above and other objects in view which will appear as thedescription proceeds, the invention. resides in the combina tion andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood.

that changes in the precise embodiment of the invention herein disclosedcan be made within the Scope of what is claimed \vithoul departing fromthe spirit of the invention.

In the accompanying dra wings Figure 1 shows in vertical section, aportion of a building,wherein the devi e form ing the subject matter, ofthis application has been mounted, parts appearing in elevation; and

Fig. 2 is a cross section taken approxi mately on the line 2--2 of Fig.1.

The numeral 1 marks a building including a roof 2, a side wall 3 and anydesired number of floors 4. Axially alined vertical pi pe sections 5 and6 are provided, there being any desired number oi the sections 5, dc

pending upon the number of floors in the.

building. The pipesections 5 and (3 have flared upper ends 7 mounted inthe floors 4-, each pipe section 5 having a reduced nozzle 8, spaced asshown at 9, peripherally, from the flared end 7 of the next lowersection, the nozzles 8 extending downwardly into the flared ends 7. Thelower pipe section 6 terminutes in an outlet 10, which, ii desired, maybe carried through the, side wall 8. At 11 there is shown a blastconduit which may be extended upwardly through the root 2, the blastconduit c aninunieating will.

"it-i blower 12 on the roof, and having a nozzle 14 entering the flaredend 7 of the adjacent pipe section 5. The blast conduit 11 and the pipesections 5 and 6 are provided with lateral outlets 15, spaced from therespective floors 4:,

In practical operation, when the tan or blower l2 is in operation, acurrent of air will be forced downwardly through the blast conduit 11,pure air passing out through the outlet 15 of the blast conduit into theroom above the uppermost door. The air adjacent the uppermost floor willbe drawn into the upper end 7 of the pipe section 5 by the draftproduced when air enters the pipe section 5 through the nozzle 14. In asimilar way, all of the rooms below the uppermost Patented May as, ar

room Wlll be ventilated, the air ultimately being discharged by way ofthe outlet 10.

It is to be noted that some of the air drawn out of the uppermost roommay be discharged through the outlet 15 of the pipe section 5 into thenext lower room, but this fact is of no great importance, since, whenthe structure is in operation, the air in all ofthe rooms will be keptso, pure, compared with the air in the rooms under ordinary conditions,that no serious or annoying re suits will be produced.

lrl a vin g thus described the invention, what is claimed is:

in a ventilating system, a building comprising floors; a plurality ofpipe sections each having its upper end mounted in one floor and havingits lower end inserted into the upper end an adjoining section andspaced peripherally therefrom to define an air inlet; a blast conduithaving its lower end inserted into the upper end of the up perinost pipesection. and spaced peripherally theretrmn to deiine an air inlet; meansas scinblcd with the conduit for creating a blast through he conduit andthrough the pipe sections, the conduit and pipe sections havin airoutlets spaced above the respecti i'c floors.

In testimony that I claim the foregoing as my own, l, have heretoaffixed my signature in the presence of two witnesses.
